- NONMETALS The nonmetallic elements are in the upper right portion of the periodic table. At roomtemperature and pressure, many of them exist as gases, but one is a liquid. Others areeither the hardest or the softest of solids.

- The metalloids or semimetals are a group of elements that contain properties of both metals and nonmetals. The highlighted elements are the metalloids. Metalloids, also known as semimetals are elements containing properties similar and midway between metals and nonmetals.

- Nonmetals are further to the right on the periodic table, and have high ionization energies and high electron affinities, so they gain electrons relatively easily, and lose them with difficulty. They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.

- 1 Most nonmetals are gases at room temperature; however, a few are solids and only one (bromine) is a liquid. 2  The noble gases are an unreactive group of nonmetals that like to exist as independent atoms, or be monatomic.

Non-ferrous metal In metallurgy, a non-ferrous metal is a metal, including alloys, that does not contain iron (ferrite) in appreciable amounts.

Nonmetal Noble gas. Apart from hydrogen, nonmetals are located in the p-block. Helium, although an s-block element, is normally placed above neon (in the p-block) on account of its noble gas property. In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.

- Nonmetals are elements that generally do not conduct electricity. They are one of three classes of elements (the other two classes are metals and metalloids.) Nonmetals are the second largest of the three classes after metals. They are the elements located on the right side of the periodic table.

Nonmetal Nonmetal, substance that does not exhibit such characteristic properties of metals as hardness, mechanical adaptability, or the ability to conduct electricity. This classification is generally applied to the chemical elements carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, fluorine, chlorine, bromine, iodine, and the noble-gas elements.

Metalloid The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables. A metalloid is a chemical element with properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid, nor is there complete agreement as to which elements are appropriately classified as such. Despite this lack of specificity, the term remains in use in the literature of chemistry.

Semimetal A semimetal or a metalloid is a chemical element. Metalloids are elements that have the propeties of both metal and non-metal elements. It might be shiny, but brittle. It might be dull, but conducts electricity. The most common semimetal is silicon. Silicon has electrical conductivity between metals and nonmetals.
